Answer:
The money you will have is $98020.
Step-by-step explanation:
It is given that grandparents deposit $2,000 each year on birthday and the account pays 7% interest compounded annually also the time is 21 years.
we will use the compound interest formula
.
For the first birthday the amount after 21 yr will be:

Similarly for the second birthday amount after 20yr will be:

likewise, the last compound will be:

The total value of such compounding would be :

![\text {Total amount}=2000[(1+(7)/(100))^(21)+(1+(7)/(100))^(20)...(1+(7)/(100))^(1)]](https://img.qammunity.org/2022/formulas/business/college/psq58oykugd71tzzfg6pl159zfhqm3fjxu.png)


The total amount just after your grandparents make their deposit is:
≈($96020+2000)
≈$98020
Hence, the money you will have is $98020.
